Replacement transaction underpriced

If your transaction fails, and the error message includes replacement transaction underpriced this happens because of a combination of nonce and gas price. Submitting multiple transactions with the same nonce but at a lower gas price than previous transaction would have this error message.

To fix this error message and successfully submit a transaction, you will need to submit a transaction with the same nonce + higher gas price than previously submitted.
